Crash in ExWorkerThreadEntryPoint

[Hartmut Birr]

Hi,    

sometimes I get a crash in
ExWorkerThreadEntryPoint/ExInterlockedRemoveHeadList. I've checked all calls
to ExQueueWorkItem. It seems that something is wrong in the tcpip/ndis
driver. There is a timer dpc which calls ExQueueWorkItem with a static work
queue item. If the worker is not execute previous the next timer call, the
item is queued for twice. Possible it is the same bug as #425.
